form-Z is an award winning general purpose solid and surfacemodeler with an extensive set of 2D/3D form manipulating and sculptingcapabilities, many of which are unique. It is an effective design tool forarchitects, landscape architects, urban designers, engineers, animators andillustrators, industrial and interior designers, and all design fields that dealwith the articulation of 3D spaces and forms. form-Z is highly responsiveto the needs of mature designers and, at the same time, novices can use itwith ease.form-Z RadioZity is the version of form-Z that includes radiosity basedrendering, provided by the LightWorks® radiosity engine. With form-ZRadioZity, the distribution of light in an environment can be simulated in aphysically accurate manner. formZ RenderZone Plus is the version of formZ that, in addition to allthe modeling/drafting/animation tools found in the basic package(described here), includes photorealistic rendering based on theLightWorks rendering engine. It offers three levels of rendering:simple, z-buffer, and raytrace. A user can start developing the image ofa 3D model at the simple level and gradually turn on features and renderit at the most photorealistic level.
